^^^ i agree if you can get away with cleaning it do that. you can go to ford and get new gasket and Orings for like $9( i also recomend doing that just incase you screw something up). also being that your truck has probly never had the egr taken out. a slide hammer will make your life a whole lot easier. it is definitly worth $80. 3 hits and that thing was out of there. the night before i pried, pulled, cussed, and yanked for an hour and got now where.
